+ Fixed problem with build paths for python tests being in the wrong location
+ Added build & run for python unit tests for escript and finley.
NOTES
+ scons defaults to building ALL targets so if will build everything, including running all tests. This behaviour can be modified by specifying the DEFAULT targets but I've not done this yet. In the interim specify the target you want.
+ Some dependencies need to be specified as scons does not figure them out automatically, though a helper scanner might be able to. These can be specified explicitly using scons Depend function. Not yet done so you can get an invalid build (especially in parallel). Examples include python depends on shared libraries, possibly a couple of library dependencies for install targets - need to verify.

1) Rob, could you please set up your editor to not put CR's into the files.
2) The import esys.bruce fails on Linux, but the rest seems OK.
Here is how things go.
If a directory (bruce say) contains an __init__.py, then import esys.bruce actually imports
the __init__.py file. One can either phoney up the namespace by then saying
from bruce import *
in __init__.py (ugly!!) or just rename bruce.py to __init__.py.
All the sub-packages need this treatment. I suggest doing it with the .py files in the
source tree rather than re-naming at build time. Any other modules in the sub-directory
can then be imported into the __init__.py in the usual way in order to make them visible
to the user. Alternatively, any module not imported to __init__.py is invisible to the user.
This is much better than mucking with PYTHON_PATH and LD_LIBRARY_PATH, which has a tendency
to make everything visible, and creates module name clashes in site-packages on occasions.
The .so associated with a sub-directory should reside with the corresponding __init__.py
that imports it.
Careful use of "from AClass import AClass" and "from ASharedLib import *" in __init__.py
is also a good method of making classes contained in submodules
look like they are in the namespace of the __init__.py, thereby hiding
the intervening module name from the user. That way esys.bruce.AClass.AClass can be morphed
into esys.bruce.AClass, eliminating the annoying intervening module namespace.

+ Added Options capability
+ All py files are now compiled and installed into lib directory hierarchy
+ scons now reads custom options from custom.py. Examples are in the scons_custom_templates directory, just copy to top level build dir and rename to custom.py
+ scons_ext.py now has some helper functions for building pyc from python and running unit tests (but only when some dependency changes).

Builds on Linux. Changes to path names in top level
SConstruct will break the windows build. I've done my best
to not change anything else that would break windows, but
something might have slipped past.
Please check the finley_UnitTests.cpp, bruce_UnitTests.cpp and
escript_UnitTest.cpp (look at the TODO).

SystemMatrixAdapterTestCase is broken and will not compile. Looks like it hasn't been updated to use Paso_SystemMatrix (used to be Finley_SystemMatrix?). I don't know the history so I'm moving the test out of the way for the moment.

Reorganise the unit test source tree and how it operates. All tests in the suite are now compiled into a single executable. If for some reason you want to run just one then use the following syntax on the command line:
finley_UnitTests --suite=Atest,AnotherTest,YetAnotherTest,...

PARTIAL WIN32 BUILD SYSTEM AND PORT
+ CppUnitTest build system and library now ported
+ make directory and other no longer necessary directories removed from this branches subversion repository
+ moved a few include files so they are now resident with sources. Build system will Install these to the appropriate location during build.
